Metagenics Algae-Sourced Calcium 90 Capsules

Unlike standard calcium supplements that simply slow down bone loss, Algae-Sourced Calcium is clinically-proven to increase bone density. A one-year study on post-menopausal women found an average bone density increase of 1.3%, an impressive result that traditional calcium supplements do not achieve.

Made from red ocean algae, this expert formula naturally contains 13 essential bone-supporting nutrients, including magnesium, boron, and strontium, to support long-term skeletal health. Easy to absorb and backed by clinical studies, it’s a smarter, more affordable and effective way to maintain strong and healthy bones.

As well as being organic and sustainably sourced, Algae-Sourced Calcium is a lot easier to take compared to traditional calcium tablets that are often large, chalky tablets that have to be chewed. Clinical studies have shown that this natural form of algae-sourced calcium increases ALP activity - a marker of bone growth - more effectively than calcium carbonate and calcium citrate - see graph below.

The vitamin D3 that is also present in Algae-Sourced Calcium is the body's preferred form as it is the same form we naturally produce in response to sunlight so is easier for the body to absorb than vitamin D2.

The Algas Calcareas used in Algae-Sourced Calcium is hand-harvested in an ecologically responsible way. It washes up on the beach naturally and is then hand-harvested within 48 hours. The crop is rotated from beach to beach to be sure not to interfere with the natural cycle of the marine algae meaning Algae-Sourced Calcium offers a natural and eco-friendly way to supplement with key minerals to support bone health.

As well as supporting normal bones, Algae-Sourced Calcium contains minerals that support many other areas of the body. Magnesium is often referred to as the 'spark of life' as it is necessary for energy production in the body, as is calcium as they both contribute to normal energy-yielding metabolism.

Calcium, magnesium and vitamin D also contribute to the maintenance of healthy teeth as well as bones and normal muscle function. Vitamin D is well known for its role in supporting immune health and the amount delivered is well above the NRV (Nutrient Reference Value) - the daily amount recommended.

AlgaeCal is the only calcium supplement supported by clinical research to increase bone density. A 2011 study published in the Journal of the American College of Nutrition examined three AlgaeCal formulations in post-menopausal women over one year, showing an increase in bone density across all groups, with an average minimum increase of 1.3%.

This is a significant result, as traditional calcium supplements only slow the rate of bone loss. DEXA scans confirmed bone density gains, setting AlgaeCal apart from conventional calcium supplements.
